Klein Tools NRHD 5-in-1 Square Lineman Deep Impact Socket Wrench

The Klein Tools NRHD 5-in-1 square deep impact socket fastens high-voltage utility distribution hardware, tightens crossarm framing bolts, secures pole steps, and spins heavy nuts onto extended all-thread rods. Built in a full-length 7.75-inch profile weighing 1.50 lbs (24.0 oz), this multi-size impact accessory incorporates 3/4-inch, 1-inch, and 1-1/8-inch square socket interfaces alongside dual alignment slots to torque curved utility hooks, eye bolts, and J-hardware. Outfitted with a 6.0-inch deep hollow shaft with a 13/16-inch inside clearance diameter to pass long protruding studs, an impact-rated steel construction compliant with ASME B107.2 specifications, and a fine-tuned 7/16-inch hex ball-detent adapter, it delivers glove-friendly, multi-stage aerial fastening efficiency for electrical linemen and power utility crews.

Best Used For:

  • Power Distribution Pole Hardware Fastening: Driving 3/4", 1", and 1-1/8" square nuts across utility pole crossarms, transformer mounts, and primary distribution framing.
  • Extended Threaded Rod and Stud Clearance: Passing long utility all-thread bolts and lag rods through the 6-inch hollow barrel to spin nuts without bottoming out.
  • Curved Hardware and Eye Bolt Alignment: Torquing pole steps, drive hooks, and suspension eyelet bolts directly using built-in small and large alignment drive slots.

Key Performance & Safety Features

  • Glove-Friendly Multi-Socket Conversion: Rapidly transitions between 3/4", 1", and 1-1/8" square fasteners without requiring linemen to remove high-voltage rubber protective gloves aloft.
  • Deep 6-Inch Hollow Barrel Clearance: 13/16-inch internal pass-through shaft accommodates long protruding bolt ends during crossarm construction and pole framing.
  • Dual Hardware Alignment Drive Slots: Dedicated large and small engagement slots seat and drive curved pole steps, eye bolts, J-hooks, and drive hooks under heavy impact torque.
  • ASME B107.2 Impact Steel Rating: Forged, heat-treated high-strength alloy steel absorbs intense rotational hammer shock from utility impact wrenches.
  • Fine-Tuned Ball Detent Retention: Included 7/16-inch hex quick-change adapter features an engineered ball tip that enhances socket retention to minimize dangerous drop hazards.
  • High-Visibility Color-Coded Bands: Double-line color bands enable rapid visual identification of socket dimensions and slotted features in dim utility bucket working conditions.

Pro-Tip: When torquing crossarm bolts over long protruding threads, ensure the 6-inch hollow shaft is fully seated over the bolt shank; this maintains true axial socket alignment and prevents side-load camming under high impact torque.
